Enum LicenceReason 

#[non_exhaustive]
pub enum LicenceReason {
    NoInputs,
    Open,
    Declared,
    ShareAlikeConflict,
    RestrictedConflict,
    NotDeclared,
    DeclarationNotOpen,
    LicenceMismatch,
}

The named outcome of licence inheritance (8.5) and of the entitlement check (10.3): a string, not an error code. Three reasons give a licence (entitled), five refuse (not entitled).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoInputs

No input receipt: the mesh’s own licence (a stored receipt, a constant, only empty slices).

Open

Open inputs only: the highest tier, and within it the identifier listed last.

Declared

One restricted licence, declared for the function and open at issued.

ShareAlikeConflict

A share-alike licence with a different share-alike licence or with any restricted one.

RestrictedConflict

Two or more different restricted licences.

NotDeclared

One restricted licence, with no declaration entry for the function naming it.

DeclarationNotOpen

One restricted licence, declared for the function, but no such entry open at issued.

LicenceMismatch

The entitlement check only: the rule gives a licence other than the receipt’s.

Implementations

impl LicenceReason

pub const ALL: &'static [LicenceReason]

Every reason, in the order of SPEC 10.3.

pub const fn as_str(self) -> &'static str

The reason as written, e.g. "share_alike_conflict".

pub fn from_name(text: &str) -> Option<LicenceReason>

Looks a reason up by its name.

pub const fn entitled(self) -> bool

Whether the reason is one of an entitled receipt (no_inputs, open, declared): the rule gave a licence.

Trait Implementations

impl Clone for LicenceReason

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for LicenceReason

impl Debug for LicenceReason

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Eq for LicenceReason

impl Hash for LicenceReason

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for LicenceReason

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for LicenceReason

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for LicenceReason

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
